Hi,

I have an Earlex 5000 hvlp spray unit. I want to spray latex paint. I have two needles: 1.5mm and a 2.0mm. I am looking for a recipe to thin the latex paint.

Thanks.

I haven’t sprayed any paint with my Earlex but I think you cut the paint with water until you get the right viscosity using the viscosity cup that came with your unit.I know there is a minimum viscosity that you have to achieve before you can spray anything out of this gun.

when spraying latex I usually end up with around 15 to 20% water. I try to get mine on the last coat to just barely be able to spray it. The color and finish look better. Too much water will dull it if it is a gloss or eggshell.

I can’t recall the name right now, but there’s a product available to thin latex paint without actually diluting it like water will do. I’ve had good luck with it.

Sawkerf—

Any luck remebering the product for thinning? I did try about 20% denatured alcohol and 10% Floetrol. (I saw a recipe that calls for another 10% of household amonia to stablize the thinned latex paint.) It worked nicely on the primer, but it seems to have robbed the satin top coat of its sheen. I may try a semigloss next or topcoat everything with an oil based satin poly. The nice thing about denatured alochol, Floetrol, and amonia is that they are cheap. Paint, unfortuantely is not cheap.

Thaks.
